6. X-Men 2 - "The Blue Binder"

Lord knows that Brett Ratner holds all the glory when it comes to having "X-Men" and "screw up" in the same phrase, but this little blunder earns Bryan Singer and his editors some credit. There are worse offences out there, but making the president look like he has the ability to transform a binder into papers is like telling us he has supepowe — Wait a second... Maybe we missed something. We need to watch this one again.
